title: Creation of a tool to assess adherence to treatments for acne.
abstract: BACKGROUND
  Acne is a disorder in which adherence has a major impact on treatment outcome.
  
  
  OBJECTIVE
  To create an easy-to-use tool to assess treatment adherence, based on a questionnaire that can be used on a daily basis by dermatologists.
  
  
  METHODS
  First, we evaluated adherence by comparing responses to a self-administered questionnaire with the dermatologist's prescription. Second, concordance was assessed between adherence and each question of a dermatologist-directed questionnaire (DDQ) administered during the consultation. Third, DDQ questions were combined to construct a mini-questionnaire, and these combinations were tested to maximize specificity.
  
  
  RESULTS
  The study included 246 patients, who were prescribed topical treatment alone, combined treatment (excluding oral isotretinoin) or oral isotretinoin alone. The mini-questionnaires for oral and topical treatments had 89% specificity for detecting poor adherence. An inappropriate answer to one question classified the patient as a probable poor compliance.
  
  
  CONCLUSIONS
  Our mini-questionnaires provide dermatologists with specific tools to rapidly identify poor compliance.
